For OSX:

for iOS:
cd build

./ios_run.sh
Also integrated the branches/StackAllocation to make it easier to multi-thread collision detection in the near future. It avoids changing the btCollisionObject while performing collision detection.
As this is a large patch, some stuff might be temporarily broken, I'll keep an eye out on issues.
It assumes a btCompoundShaps (where the childshapes are the pre-fractured pieces)
The btFractureBody is a class derived from btRigidBody, dealing with the collision impacts and connectivity/propagating the fracture.

This is preliminary work, can be used as a starting point to implement your own fracture.
